Heat Pumps & Clean Heat
Cold-climate heat pumps.
Sized to the house, not the old furnace.
A cold-climate air source heat pump heats and cools a Long Island home on electricity instead of oil or gas. EnergiSense sizes it from a Manual J load after the envelope is tight, then verifies the PSEG Long Island rebate tier before it goes on the proposal.
- Ducted or ductless
- Manual J sizing
- PSEG rebate tier verified
- Pairs with solar + battery
Heat pump service
Sized right.
Rebate verified. Solar-ready.
Load calculation, not square footage
PSEG requires a Manual J and a system sized to 100 to 120 percent of the heating load for the whole-house rebate.
Rebate confirmed before it is counted
Market rate, disadvantaged community, moderate income, or low income: the tier is verified for your address first.
Heat pump plus solar plus battery
The same company designs the heat pump load, the solar array that feeds it, and the battery that shifts it.
Heat pump decision
Load, layout, rebate.
In that order.
The heat pump conversation starts with the measured load and the rebate tier for your address, then moves to ducted or ductless, then to the electric plan that feeds it.
01
Problem check
Long Island homeowners are replacing aging oil and gas systems while electric rates and rebate rules keep changing. EnergiSense starts with the existing system, roof condition, utility account, and timeline so the recommendation fits the property.
02
Scope separation
Solar, roofing, storage, removal, and repair work are separated in the proposal so the homeowner can see what is urgent and what can wait.
03
Roof and electrical review
Roof age, attachment risk, inverter location, panel layout, shutoff rules, and access are checked before promising a simple install or repair.
04
Utility math
PSEG, Con Edison, or local utility details are reviewed against the actual bill instead of generic New York savings claims.
05
Manufacturer path
Equipment brand, cold-climate rating, ducted or ductless layout, integrated controls, electrical capacity, and rebate paperwork are reviewed before the heat pump proposal is issued.
06
Next appointment
The heat pump has to be sized to the post-insulation load and the rebate tier has to be confirmed before the price is real. The intake asks for a quote path and preferred site-visit window so the page can turn ranking traffic into a real appointment.
PSEG rebates, 2026
Whole-house rebate tiers PSEG Long Island publishes.
PSEG Long Island lists whole-house cold-climate air source heat pump rebates by income and location, with a Manual J load calculation and a participating contractor required. Integrated controls are required unless the fossil-fuel system is removed.
- Market rate: $4,000.
- Market rate in a disadvantaged community, or moderate income under 80% of area median income: $5,000.
- Low income under 60% of area median income: $7,500.
- System sized to 100 to 120 percent of the heating load; 2026 income examples for a household of four are $98,925 (low) and $131,900 (moderate).
Sizing
Manual J after the envelope, not before.
The rebate requires a Manual J load calculation, and the load changes once the house is air sealed and insulated. Sizing the heat pump to the tightened house means a smaller, cheaper unit that runs longer, steadier cycles.
- Run the assessment and complete envelope work first where the payback supports it.
- Calculate the Manual J on the post-upgrade house.
- Select cold-climate-rated equipment to 100 to 120 percent of that load.
- Document the calculation so the PSEG rebate paperwork is complete.
Ducted vs. ductless
Reuse the ducts if they are worth reusing.
Existing ductwork saves money only when it is sealed and sized for the new air handler. Duct leakage testing decides whether the ducted path or a ductless zone layout is the better spend.
- Ducted: replaces the furnace or air handler, reuses sealed ducts, one outdoor unit.
- Ductless: wall or ceiling heads per zone, no ductwork, ideal for radiator and baseboard homes.
- Hybrid: ducted for the main floor, ductless for additions or finished attics.
- Integrated controls keep the old boiler or furnace as backup below the set point.
Electric plan
The heat pump is one third of an all-electric house.
Once heating moves to electricity, the electric bill grows and the solar array and battery need to be designed around it. EnergiSense designs all three together so the panel, the array, and the rate plan line up.
- Confirm panel capacity and the 240-volt circuit for the heat pump.
- Size the solar array to the new heating load under PSEG net metering.
- Use a battery to shift usage into off-peak and super-off-peak windows.
- Model Rate 580 against the standard residential rate on your actual usage.
Heat pump vs. oil or gas
What changes when heating goes electric.
| Factor | Cold-climate heat pump | Oil or gas system |
|---|---|---|
| Fuel | Electricity, which solar can generate on site. | Delivered oil or piped gas at market price. |
| Cooling | Included; the same equipment cools in summer. | Separate central air or window units. |
| Rebates | PSEG whole-house rebate of $4,000 to $7,500 by tier, plus Rate 580. | None for like-for-like replacement. |
| Backup | Existing system can stay as backup with integrated controls. | Is the primary system; no electric backup. |

Heat Pumps & Clean Heat FAQ
Questions before
the appointment.
What heat pump rebate does PSEG Long Island offer in 2026?
PSEG Long Island publishes whole-house cold-climate air source heat pump rebates of $4,000 at market rate, $5,000 for a market-rate home in a disadvantaged community or a moderate-income household under 80% of area median income, and $7,500 for a low-income household under 60% of area median income. The system must be sized by a Manual J load calculation to 100 to 120 percent of the heating load, the equipment must be on the NEEP cold-climate air source heat pump list, integrated controls are required unless the fossil-fuel system is removed, and the work must be done by a PSEG participating contractor. EnergiSense confirms the installing contractor's program status and your tier before any rebate is counted on the proposal.
Do cold-climate heat pumps work in Long Island winters?
Yes. PSEG Long Island describes cold-climate air source heat pumps as more efficient and cleaner than older fuel oil and propane systems and recommends keeping the existing heating equipment only as a backup, switched in by integrated controls below about 15°F. A properly sized cold-climate unit carries the house through a typical Long Island winter on its own.
Ducted or ductless: which one should I get?
If the house already has central air or forced-air ducts in good condition, a ducted heat pump usually replaces the air handler and reuses the ducts after they are sealed. If the house has radiators or baseboard and no ducts, ductless mini-splits serve each zone without new ductwork. Many Long Island homes end up with a mix. The assessment and a duct-leakage test decide.
What is PSEG Rate 580?
Rate 580 is PSEG Long Island's Residential Electric Heating rate. PSEG's heat pump FAQ describes a 40 percent energy delivery charge discount on all usage above 400 kWh per month from October through May for qualifying electric-heat customers. EnergiSense models the rate on your proposal using your actual usage.
Is the federal 25C energy efficiency tax credit still available?
The federal Energy Efficient Home Improvement Credit (25C) ended for property placed in service after December 31, 2025, so it does not apply to 2026 installs. State and utility programs are the incentives that still move the number on Long Island. Confirm your own tax position with a tax professional; EnergiSense models only the incentives it can verify for your address.
Which heat pump brands do you install?
EnergiSense designs around cold-climate-rated equipment from established manufacturers such as Mitsubishi, Bosch, Fujitsu, Gree, and Midea, chosen for the layout and load of the house rather than a single-brand catalog. Brand, model, and cold-climate rating are listed on the proposal.
Do I need an electrical panel upgrade for a heat pump?
Sometimes. A whole-house heat pump adds a significant 240-volt load, and older 100-amp panels may need to be upgraded to 200 amps, especially if solar, a battery, or an EV charger are part of the plan. EnergiSense is the electrical contractor on its own solar installs, so panel capacity is checked in the same review.
